First you have to add and subtract everything on both sides that have common terms.
[tex]33+15w=3w-w+4w[/tex] then becomes
[tex]33+15w=6w[/tex]
Then you subtract 15w from each side and get
[tex]33=-9w[/tex]
Divide each side by -9 and get
[tex] \frac{-33}{9}=x [/tex]
which we can simplify by 3
[tex] \frac{-11}{3} =x[/tex]
